Cardiovascular disease, and in particular ischemic heart disease, is the principal cause of morbidity, functional disability, and mortality in patients with non-insulin-dependent (type II) diabetes. The main risk factors for the macrovascular complications of diabetes are dyslipidemia, hypertension, and cigarette smoking. Although degree of hyperglycemia is a risk factor for microvascular complications, it is not a prominent risk factor for macrovascular complications. Nevertheless, there are theoretical reasons for believing that glycemic control could lower cardiovascular risk. For example, glycemic control may both improve clearance and suppress hepatic overproduction of very-low-density lipoprotein. Moreover, there is direct empirical evidence that improved glycemic control can favorably alter lipid profiles in type II diabetic patients. Despite this, the only clinical trial that has assessed cardiovascular mortality as an end point in diabetic subjects (i.e., the University Group Diabetes Program) failed to demonstrate a benefit of glycemic control. In this study, the insulin-variable group, which achieved sustained glycemic control relative to the placebo group, had essentially the same cardiovascular mortality as the latter group. All of the conventional lipid-lowering agents have been shown to produce favorable changes in lipid profiles in diabetic subjects. However, the optimum regimen remains to be defined. Metabolic differences between diabetic and nondiabetic subjects mean that the optimum lipid-lowering regimens for the two categories of patients may differ. For example, nicotinic acid, which is a powerful lipid-altering drug, may worsen glucose intolerance. The characteristic lipid abnormalities in type II diabetic subjects are hypertriglyceridemia and low high-density lipoprotein cholesterol, not hypercholesterolemia. Although the role of hypertriglyceridemia as a cardiovascular risk factor in the general population has been questioned, there is evidence that this lipid abnormality may play a stronger role in diabetic subjects. For all of the above reasons, there is an urgent need for large-scale clinical trials assessing cardiovascular end points and testing various strategies of improving lipid profiles in diabetic subjects, particularly given the fact that all of the current generation of lipid-lowering trials have systematically excluded diabetic patients.
